Corso Italia is a neighbourhood in Toronto, Ontario, Canada, situated on St. Clair Avenue West, between Westmount Avenue (just east of Dufferin Street) and Lansdowne Avenue. It is contained within the larger city-recognized neighbourhood of Corso Italia-Davenport, which is bounded on the west by the CNR tracks, on the north by a line north of Morrison Avenue, on the east by Westmount Avenue and Oakwood Avenue, and on the south by Davenport Road.

The community is the eastern half of what was earlier known as Earlscourt. Earlscourt was originally settled by British immigrants in 1906, and was annexed by the City of Toronto in 1910.

During the late 1950s a large wave of Italian immigrants, in addition to Italians from College Street, moved to Earlscourt and the surrounding area. Corso Italia has been a Business Improvement Area (BIA) in Toronto since 1984.
